a) Calculate the approximate decimal reduction time (D-value) for each of the two antimicrobials tested. The
D-value is the time it takes to kill 90% of the microbes in a sample. (Hint: What is the percent difference
between 10 and 102?)
b) You need a disinfectant that works within 30 seconds. Can either of these be used?
